The present invention relates to nonwoven webs or fabrics. In particular, the present invention relates to nonwoven webs having superior abrasion resistance and excellent softness characteristics. The nonwoven materials comprise monocomponent fibers having a surface comprising a polyethylene, said nonwoven material having a fuzz/abrasion of less than 0.7 mg/cm3. The present invention is also related to fibers having a diameter in a range of from 0.1 to 50 denier, said fibers comprising a polymer blend, wherein the polymer blend comprises: from 40 weight percent to 80 weight percent (by weight of the polymer blend) of a first polymer which is a homogeneous ethylene/α-olefin interpolymer having: a melt index of from about 1 to about 1000 grams/10 minutes, and a density of from 0.870 to 0.950 grams/centimeter3, and from 74 to 20 percent by weight of a second polymer which is an ethylene homopolymer or an ethylene/α-olefin interpolymer having a melt index of from about 1 to about 1000 grams/10 minutes, and preferably a density which is at least 0.01 grams/centimeter3 greater than the density of the first polymer.
A nonwoven material comprised of fibers having a surface comprising a polyethylene blend, said fibers being selected from the group consisting of monocomponent fibers, bicomponent fibers or mixtures thereof, said nonwoven material having a fuzz/abrasion less than or equal to 0.0214(BW)+0.2714 mg/cm2 when the material comprises monocomponent fibers and said nonwoven material having a fuzz/abrasion less than or equal to 0.0071(BW)+0.4071 mg/cm2 when the material consists of bicomponent fibers, wherein BW is the basis weight of the nonwoven material, wherein the fibers are from 0.1 to 50 denier and wherein the polymer blend comprises:
A fiber having a diameter in a range of from 0.1 to 50 denier, said fiber comprising a polymer blend, wherein the polymer blend comprises:
A fiber having a diameter in a range of from 0.1 to 50 denier, said fiber comprising a polymer blend, wherein the polymer blend comprises:
